And now Charlie still doesn't make up his mind, and Sam kills that zombie. Charlie feels humiliated and decides to make up for it next time. When Milo enters the building, he doesn't take his time to identify the silhouette he sees in the door and zerkers it to shreds.

Yeah though its a webcomic, a medium designed to keep the reader engaged and interested every update. Look at Order of the Stick, or even Penny Arcade. If Jenny wants to get new audience she better get them engaged with them just by whatever the update is at the time.

A lot of time's she uses filler to show her artwork then what the story really needs, though hoping this will change to be more balanced

Criticising the art that you view is your right, in fact it's a healthy part of the exchange between the artist and the public, but you ought to watch your tone. There is no place to be condescending, you are not a savior or an authority that can suddenly pop up and order every perceived problem away. It's not like you're the first who wished Jenny would draw faster, (I believe Jenny wishes that too) nobody is gaping in awe whispering "This is what we needed all along! What a genius!" the rest of us just happen to know that Jenny is the one who knows how much time and energy Jenny has to put on it.

Instant gratification is what you're after, right? Maybe this isn't the comic for you if you don't have the patience. Or, you can stop reading the comic for a couple months, come back, and BAM! there's a bunch for you to read. (Wash, rinse, repeat)

Personally, I love the graphic novel feel. Like I'm reading a movie. I like the building up of the characters and getting a sense of the location of the characters; it just appeals more to the emotions, ya know? I would assume that what you want to see is a lot more action, but if a movie is all action/action/action, it would be a bad movie.
